The Democrats have their best chance in 10 years to make major gains in the congressional elections on November 7, 2006 while Republicans are striving to retain control of both the House and the Senate. For Republicans to lose control of both houses of the legislature, the Democrats need net gains of 15 House seats and six Senate seats. This article discusses how the congressional elections are taking place against a backdrop of diminishing confidence in the performance of Congress, considering the view among the voters in opinion polls that it would be better for Congress to be in Democratic rather than Republican hands as they examine the performance of their own members of Congress. This article also describes major changes in congressional elections to both parties in 1974, 1980, and 1994, discusses how to keep track of the congressional elections, and presents 24 House of Representatives races and eight Senate races between the two parties.
